UNITED STATES PATENT OFFICE TWO-COLOR ROCKING MAGAZINE Application March 5,

12 Claims.

This invention relates to improvements in weft replenishing looms and it is the general object of the invention to provide simplified mechanism for presenting for transfer a plurality of distinctive types of reserve bobbins.

In the weaving of certain fabrics in automatic looms it is necessary to provide different types of weft in order that patterned effects may be Woven crosswise of the fabric. This has been accomplished heretofore in a so-called stationary magazine in which are mounted stacks of distinctive reserve wefts over releasing mechanism in the form of cradles, and color controls have been necessary to select'the correctly colored weft. It is an important object of my present invention to eliminate the cradles and their controls as heretofore employed and provide'a rocking magazine having a plurality of stacks of reserve bobbins so arranged that the lowest bobbin of each stack can be moved to transfer position by rocking of the magazine.

`It has been proposed heretofore to use rocking magazines, but in most instances mechanisms of this type have oscillated with each shifting of the shuttle boxes at the opposite end of the loom with the result that the bobbins are subject to a vibration which interferes with proper thread control. It is a further object of my present invention to provide a loom wherein the magazine is normally at rest and is rocked only at the time of transfer. In this connection it is a further object of my invention to have the magazine normally placed for transfer of one color so that when that color is called there is no rocking of the magazine, the latter rocking only when some other color is called.

It occasionally happens that a shuttle will fail to be properly boxed on al transferring beat of the loom, in which case it is necessary to revoke the previous setting of the magazine and transfer. It is a still further object of my invention to set the magazine for transfer by a train of mechanism including a connection which first operates to set the magazine and then operates to break the train for the purpose of permitting revocation of the transfer without damaging the control connections for the magazine.

Certain features of my invention are more par ticularly adaptable for use with so-called fiat bobbins the weft mass of which is non-circular in transverse cross section, the horizontal axis for the section being greater than the vertical axis. When such bobbins are used provision must be made for presenting them properly positioned for cooperation with the transfer arm. When in 1937, Serial No. 129,245

transfer position the greater transverse axis of the bobbin barrel should preferably be inclined downwardly and forwardly at a given angle determined by the aids of the transferrer and the location of the shuttle under the magazine. In a rocking magazine this angular relation will be subject to change due to the angular motion of the magazine as a whole, and it is a further object of my further invention to provide guides and supports for the various stacks of bobbins so proportioned and positioned as to present a bobbin of the flat type in correct transfer position for the different angular settings of the magazine.

While the magazineillustrated is shown adapted for fiat bobbins yet certain features of my ininvention are not limited to such bobbins.

With these and otherobjects in View which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter set forth.

In the accompanying drawings, wherein a convenient embodiment of my invention is set forth,

Fig. 1 is an end elevation of a portion of a loom having my invention applied thereto, the lay;- shuttle box and shuttle being shown in section,

Fig. 2 is an enlarged detailed end elevation of the upper left hand part of Fig. l,

Figs. 3 and 4 are operating views of the lower portion of the magazine showing the latter inv different positions,

Fig. 5 is a plan view of a flat bobbin of the type usable in the magazine illustrated,

Fig. 6 is an end elevation of parts of the magazine taken from the center of the loom, and

Fig. 7 is a diagrammatic front elevation of a loom having my invention applied thereto.

Referring to the drawings, I have shown a loom frame lil and a lay Il movable backwardly and forwardly by a top or crank shaft l2. Thev lay is mounted on swords i3 pivoted at I4 and carries a shuttle box l5 to receive either of two different shuttles, one active shuttle S being shown in Fig. 1. These shuttles are rendered active alternately by shuttle box mechanism shown generally at I6 in Fig. 'l located at that side of the loom opposite the magazine to be described.

A bottom shaft 20 running half as fast as the top shaft carries a grooved cam 2l to move a roll 22 on actuator lever 23 rocked regularly by the cam. To theforward end of the lever there is pivoted a lifting dog 24 which normally has an idle ascending motion on those beats of the loom when transfer is not called. Lever 23 rocks on a xed stud 25 on which there is also pivoted a secnd or lifting lever 26 normally at rest and having the rear end thereof provided with a laterally projecting stud 21. Lever 26 has mounted thereon a solenoid 28 and a color selector mechanism designated generally at C including two control fingers 29 and 3l). These fingers are normally out of the path of a small cam 3| on the dog 24, but when one or the other of the fingers is set for transfer and is over cam 3|, rising of the forward or left hand end of lever 23 as viewed in Fig. l will cause the dog to be cammed by the set finger registering therewith into lifting relation with a shoulder 26 on the front end of lever 26. When this occurs a rod 32 pivoted to lever 26 is raised for a purpose to be described.

The setting of the fingers 29 and 38 is effected by a weft detector D which in the present instance is of the electrical type and suspended from parallel links 33 hung from a fixed support 34 on a stationary transfer stud 35. The weft detector may be of the type shown in patent to Payne No. 1,924,197 and a circuit Iis closed through the detector when the weft W on the active bobbin B becomes substantially depleted. At this time the following circuit will be closed; battery P, wire 36, detector D, wire 31, solenoid 28, and wire 38 connected to the battery. Current flowing in this circuit will energize the sclenoid and cause the latter to set one or the other of the fingers 29 or 38 for control of the dog 24.

The fingers are mounted on a carriage 48 movable longitudinally on lever 26 in time with some part coordinated with the shifting shuttle boxes at the opposite end of the loom. As shown herein this part is a lever 4| connected to a link 42 and flexible cable 43 which extends across the loom and is connected to drop box mechanism |6, see Fig. 7. Lever 4| pivots about a. stud 45 on a stationary holder 46 secured to the stud 25, and the upper part of lever 4| is connected to the slide 48 bymeans of a rod 41. Passing through part of the lever is a hook 48 the lower end of which is adapted for cooperation with the stud 21 for certain of the transfers. The hook is secured to the lower end of rod 49 which is depressed by the rocking of lever 26 when the hook is under stud 21. A tension spring 50 is connected to the holder 46 and lever 4| to hold the latter yieldingly in the position shown in Fig. 1. The lever 4| may be rocked in a right hand direction around stud 45 against the action of spring 58.

'Ihe matter thus far described, with the exception of the mounting for the weft detector, may be the same as that heretofore used and shown more fully in prior Patents Nos. 2,054,192 and 2,054,173. A distinction is to be found between these patents and my present invention, however, in that there is but one hook 48, the reason for which will be pointed out hereinafter.

Referring more particularly to my invention, I provide a magazine M pivoted on a fixed stud 60 and having front and back compartments 6| and 62, respectively, for reserve bobbins. A lever 83 with a xed pivot 64 is attached to rod 49 and also to a forwardly extending rod 65 carrying a spring 66 and passing through a stud 61 against which the spring presses, see Fig. 6. The rear end of the spring is positioned by a collar 68 on the rod 85 and a second collar 69 on the rod 65 engages the stud 61 to limit forward expansion of the spring.

The magazine includes an inner plate 15 carrying stud 61 and having front and back bobbin butt compartments 16 and 11, respectively, and the magazine also has two outside end plates 118 and 19 which are in front of and behind the axis of the magazine, respectively. Tie rods 88 may be employed to secure the end plates to the inner plate to cause the plates to rock as a unit about the stud 68. The rear end plate 19 has a smooth weft thread guide surface 8| along the front edge thereof, while the front plate 18 has a similar surface 82 along the forward edge thereof. The thread guides surfaces so disposed facilitate loading of bobbins into the magazine.

While my invention can be employed in connection with the usual type of bobbin having a cylindrical barrel, yet I have illustrated the magazine as adapted for use with the so-called fiat bobbin shown in Fig. and having a barrel F the horizontal transverse axis of which is greater than the vertical axis. The bobbin has a head 85 provided with rings 86 and having parallel or slab surfaces 81, one of which shows in Fig. 5.

The front end plate 18 has a bobbin tip receiving groove 9D slightly wider than the thickness of the bobbin tip, and this groove curves rearwardly toward an enlargement 9|. As the bobbins descend they turn as their tips move along the curved part and the major transverse axis of the bobbin barrel ap-proaches the horizontal. When in this position the bobbin tip rests on a yieldable tip support 92 pivoting about a stud 93 carried by the plate 18. A leaf spring 94 mounted on a plate 18 pushes outwardly on the top of the 30 support 92 and holds a supporting ledge 95 with a flat upper surface 96 yieldingly under the bobbin tip. At transfer the ledge moves outwardly in a direction longitudinally of the axis of the bobbin being transferred. In a similar manner, rear end 35 plate 19 has a bobbin tip groove 91 which curves forwardly to guide a descending bobbin over and onto a fiat top surface 98 of a yielding support 99 pivoted on stud |89 and positioned by leaf spring |0| similar tospring 94.

The surfaces 96 and 98 are not parallel, the angular distance between their planes being substantially equal to the angle through which the magazine rocks. The reason for this relationship is due to the desirability of having the major transverse axes of the bobbin barrels at the same angle with respect to the horizontal when the bobbins on the supports are in transfer position.

'Ihe yielding supports for the bobbin heads or butts are shown in Figs. 4 and 6. support |85 has an upper guide surface |06 for the bobbin rings and a depending lip |91 to guide the bobbin head during transfer. Support |05 is pivoted at |08 to the innerV magazine plate 15 and is held yieldingly in rear position by spring |89. The distance between lip |01 and an intermediate guide integral with plate 15 is less than the diameter of the rings, and at transfer the support rocks forwardly to allow the lowest bobbin in compartment 16 to be moved into the shuttle. The rear end plate has a butt support |2 with a lip I3 and is pivoted at |4 and held yieldingly forward by spring |I5. Surface ||6 inclines forwardly and downwardly and lip I3 is normally near enough to guide I0 to hold the lowest bobbin in compartment 11. Since the bobbin rings are circular it is not necessary that surfaces |86 and ||6 sustain the same relationship as that described for the tip supports.

The transferrer arm |28, shown more particu.

larly in Figs. l, 2 and 4, is pivoted on stud 35 and has pivoted thereto at |23 a carrier |22 to which is bolted a transfer latch |24 with a notched rear end for engagement with a bunter |26 on the lay |I.

|33 on lever |34 which moves about a stub shaft |35 rotatable in a magazine supporting bracket |36. The lower end of the latter1v is mounted on the loom frame and the upper end thereof is attached to the loom arches, as suggested in Figs. 1 and 2. An arm |31 secured to the inner end of the shaft |35 has a connection |38 with a link |39 moving about an axis |40 on the bracket |36, and a spring |4| tends to hold the arm |31 against one of two spaced stops |42 so positioned as to hold the lever |34 yieldingly locked in either of two extreme positions.

' A shuttle feeler |43 is pivoted on step shaft |44 vand is connected by a link |49 to the lever |31 of the yielding lock of which spring |4| is a part. This shuttle feeler is normally forward out of the path of the shuttle when the transfer latch |24 is down or in non-transfer position, and can be set along shaft |44 the desired distance, depending upon the.length of the shuttle and the amount of shuttle rebound permissible.

The rear end |45 of lever |34 carries a laterally extending pin |46 to enter a hook |41 on the upper end of a rod head |48 secured to the rod 32 already described.' A lifting shoulder |50 on rod head |48 is spaced from the hook |41 to define an opening through which the pin |46 may pass. A light spring |52 has its forward end connected to the transferrer arm while the rear end connected to a return lever |53 pivoted to the transferrer arm at |54 and engaging the rear part of head |43. The lower front part of the head has an inclined cam |55 to engage a stud |56 on the transferrer arm for the purpose of moving head |48 rearwardly at transfer to disconnect the head from the pin |46. The customary torsion spring |51 acts in the usual manner to hold the transferrer arm up. as shown in Fig. 2. A holding surface |60 on the head extends downwardly from area |55 for a purpose to be described.

Fig. 6 shows means to control the rocking movements of the magazine. A rear stop screw |65 adjustable vertically in bracket |36 engages a lug |66 of the inner magazine plate 15 behind the magazine axis, while a second screw |61 in the bracket engages a second lug |66 of the plate 15 in front of the axis. A return spring is located between the magazine and bracket and tends to hold the magazine yieldingly in rear position. This spring is weaker than spring 66 and yields to the action of the latter when the magazine is to be rocked. If the rod 65 continues to move after stop screw |61 arrests the magazine, spring 66 yields to prevent breakage. Spring |10 acts through rods 65 and 46 to lift hook 48 after lowering thereof by stud 21.

In operation, the shuttle boxes at the left hand end of the loom will shift in response to the pattern mechanism not shown to rocklever 4| from one extreme position to the other. This rocking occurs before the active shuttle reaches the box under the magazine and therefore the color control mechanism C will have one or the other of the control fingers 29 or 30 in register with the cam 3|. Spring |10 holds the magazine so that the lowest bobbin in the rear stack will be over the shuttle S. Rod 32 and latch |24 will be down vand the shuttle feeler will be forward. When the lay moves forwardly with an empty shuttle under the magazine the detector D will close'the previously traced circuit` and assuming thaty the shuttle corresponds to the front stack of bobbins in the magazine, the control element 29 will be set for transfer.. The shuttle will be picked to the opposite or box end of the loom and if it is to forward position shown in Fig. 1 so that when the dog 24 rises, the finger 29 will engage cam 3| to direct the dogunder shoulder 26.

Lever 26 then rocks to lower pin 21 and hook 48 which under these conditions is under pin 21, and lever '63 turns to move the magazine in a left hand direction as viewed in Fig. l to place the lowest front bobbin for transfer. Rocking of lever 26 also raisesv rod 32 to force shoulder |50 against stud |46` and rock lever |34 in a left hand direca tion to raise transfer latch |24 into the path of the bunter |26, see Fig. 6. The turning of shaft |35 with lever |34 also moves the shuttle feeler |43 rearwardly into shuttle feeling position. As

the connection |38 rises to a point above a liner:v

joining centers |35 and |40, spring |41 will give lever |34 a quick advance motion to move the pin |46 away from shoulder |50.

At about this time surface |55 of the head |48 engages the stud |56 on the transferrer arm and r, moves the head rearwardly against the action of spring |52. Stud |46, being opposite the opening |5|, passes through the latter as the head |48 moves rearwardly. In this way the train of connections between the lever 26 and@l those parts controlled by rocking of shaft |35 is temporarily broken.

As the lay advances the bunter will engage the latch to rock the transferrer arm |20 and cause the lowest bobbin in the front compartlwill move against its spring away from the intermediate bobbin guide ||0 and the corresponding tip support willV swing outwardly in a direction longitudinally of the axis of the bobbin against the action of the associated leaf spring. For further details of the transferring action with respect to flat bobbins, reference may be hed to my copending application Serial No. 97,96

-remain active the slide 40 will remain in the .115

.55 During the time that the lay is moving latch `|24 forwardlystud |56 will move down along surface to maintain head |48 in rear position. As the lay nears front position it strikes the shuttle feeler to reset the latter in forward position, thereby rocking shaft |35 to release the latch |24. Slot |32 permits rocking of lever |34 while the latch is still engaging the lay bunter. During this resetting of lever |34 stud l |46 moves through opening |5|.

As the lay recedes the transferrer arm will rise lunder the action of spring l51 and when the stud 56 starts to move up the incline |55, spring of Fig. 2 for the next transfer. After transfer l75 is completed and the transferrer arm is raised to clear guide HD, cam 2| will act to permit spring |10 to rock the magazine back to normal position. It is to be understood that the cam 2| must maintain the magazine in position throughout the transfer, and it is for this reason that the pin |46 must be capable of disengagement with head |48 should transfer be revoked.

Should the shuttle not be properly boxed it is necessary to revoke the transfer and this will be accomplished by the forward motion of the shuttle feeler which will rock shaft |35 with resultant dropping of the latch |24 out of the path of the bunter on the lay. The rocking of lever |34 under these conditions will move the stud |45 along a downwardly and forwardly extending arcuate path, but at this time the rod head |48 is in rear raised position, hence said stud |46 will move in front of shoulder |50.

If transfer is to be from the rear stack the color control C Will be moved so that linger 30 is inV register with cam 3| and hook 48 will move rearwardly from under stud 21. Under these conditions the same operation previously described takes place with the exception that hook 4B will not be lowered, since the magazine is not to be rocked.

The particular means for breaking the connection between the lever 26 and the transfer mechanism, including the head |48 and the space 5| through which the stud |46 passes, is not claimed herein but is made the subject matter of a separate application filed on March 17, 1937, by Cederlund Serial No. 131,430.
